These are some notes I put together in one place for my Android exploits.

Misc

  • F-Droid is a widely used repository and safe to use.
• Android Keystore system  |  Android Developers
  
  • The Android Keystore system lets you store cryptographic keys in a container to make them more difficult to extract from the device
  • The keystore system is used by the KeyChain API, introduced in Android 4.0 (API level 14).
  • When an App says the tokens are stored in the Keystore this means it is stored on your Google Drive in a hidden folder that can only be accessed by the same app that created the folder.
